The traditional method has some disadvantages such as low network coverage and high energy consumption in fiber laser sensor network node deployment, which affects the performance and service life of optical fiber network. A method based on perceptual probability model is proposed to deploy mobile relay node in fiber laser sensor network . Firstly, the perceptual probability model is constructed according to the two important indexes of the current network coverage and energy consumption in the target area, and the comprehensive perceptual probability information around the existing network nodes is obtained. Then, the perceptual probability model is used to increase the mobile relay nodes appropriately to optimize the optical fiber transmission The topological structure of the sensing network is determined by calculating the moving probability of the mobile relay node, and the deployment of the mobile relay node in the fiber laser sensing network is completed. Finally, the experimental results show that the proposed method can improve the performance of the fiber laser sensing network Coverage, save node energy consumption, extend the service life of the network.
